尊敬的专家:

我已初始化不同的内存节点、 ../../k3-am62x-r5-sk.dts并且提供了以下代码:

#include "k3-am62x-sk.dts"
#include "k3-am62x-sk-ddr4-1600MTs.dtsi"
#include "k3-am62-ddr.dtsi"

#include "k3-am62x-sk-u-boot.dtsi"
#include "k3-am62x-r5-sk-common.dtsi"
#include "k3-am62x-sk-binman.dtsi"

/ {
	memory@80000000 {
		device_type = "memory";
		/* 2G RAM */
		reg = <0x00000000 0x80000000 0x00000000 0x80000000>;
		bootph-pre-ram;
	};
};


/* / {	
 *		 memory@80000000 {
 *		 device_type = "memory";
 *		 /* 1G RAM */
 *		 reg = <0x00000000 0x80000000 0x00000000 0x40000000>;
 *		 bootph-pre-ram;
 *	 };
 * };
 */
 
 
/* / {	
 *		 memory@80000000 {
 *		 device_type = "memory";
 *		 /* 4G RAM */
 *		 reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
 *		       <0x00000000 0x80000000 0x00000000 0x80000000>;
 *		 bootph-pre-ram;
 *	 };
 * };
 */
 
/* / {	
 *		 memory@80000000 {
 *		 device_type = "memory";
 *		 /* 8G RAM */
 *		 reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
 *		       <0x00000000 0x80000000 0x00000000 0x80000000>,
 *		       <0x00000000 0x80000000 0x00000000 0x80000000>,
 *             <0x00000000 0x80000000 0x00000000 0x80000000>;		       
 *		 bootph-pre-ram;
 *	 };
 * };
 */

如果不同 RAM 大小的初始化正确、请指导我 如何使用 defconfig 文件配置这些节点/文件?
